VERY LITTLE USE NEAR NEW. The Rock Island Armory M1911-A1 is a modern commercial version of the classic M1911A1 pistol design. It is manufactured by Armscor and sold under the Rock Island Armory (RIA) brand. These pistols are based on the original U.S. military M1911A1 pattern and are generally known for offering a traditional 1911 design at a relatively affordable price point. Typical Specifications Caliber: Usually .45 ACP (other chamberings exist) Action: Single-action, semi-automatic Barrel length: 5 inches (Government-size model) Magazine capacity: Typically 8 rounds Steel frame and slide Series 70-style design on many models M1911 vs. M1911A1 The original M1911 was updated into the M1911A1 during the 1920s. Changes included: Shorter trigger Arched mainspring housing Relief cuts behind the trigger Longer grip safety spur Improved sights and hammer geometry Reputation Owners and reviewers generally view Rock Island 1911s as solid entry-level 1911 pistols. They are often praised for: Good value for money All-steel construction Compatibility with many standard 1911 parts Reliable operation when properly maintained Some shooters note that fit and finish may not be as refined as higher-end 1911s from premium manufacturers, but many report excellent reliability and accuracy for the price. Important Distinction Rock Island Armory (the commercial firearms brand) is not the same entity as Rock Island Arsenal, the historic U.S. Army arsenal in Illinois. The similar names often cause confusion.
